1. A method for making a solid oxide fuel cell assembly (SOFC), comprising:
forming a functionalized zeolite templated carbon (ZTC), comprising:
forming a CaX zeolite;
depositing carbon in the CaX zeolite using a chemical vapor deposition (CVD) process to form a carbon/zeolite composite;
treating the carbon/zeolite composite with a solution comprising hydrofluoric acid to form a ZTC; and
treating the ZTC to add catalyst sites, forming the functionalized ZTC; and
incorporating the functionalized ZTC into electrodes, comprising:
forming a mixture of the functionalized ZTC with a calcined solid oxide electrolyte; and
calcining the mixture;
forming an electrode assembly;
forming the SOFC assembly; and
coupling the SOFC assembly to a cooling system.
